This Washington University project will develop and test a staged, pressurized oxy-combustion process and evaluate the economics of the system. The process incorporates fuel-staged combustion mode for power plants designed for carbon management. The approach permits control of temperature and heat flux associated with oxy-combustion. The potential benefits of the process are higher efficiency and lower capital and operating costs. Reduced gas volumes, oxygen and auxiliary power demands, and increased CO2 purity in the flue gas are additional anticipated benefits.

Project Benefits

This project is developing a staged, pressurized, oxy-combustor system. Fuel-staged combustion uses excess oxygen as a diluent to manage peak combustion temperatures, and combined with high pressure operation, has the potential to reduce capital and operating costs relative conventional systems. Specifically, this project will develop and test a laboratory-scale pressurized oxy-combustor to support design, development, and testing of a small-pilot scale prototype.
